Many people in their 30s are even thinking: In order to respond to the national call for late marriage and late childbirth, what if I can’t have a baby by then, and I have to hand over my hard-earned mountain to the state? Don’t worry, you still have to do a fertility assessment test. In short, it is to look at the condition of the sperm and eggs. However, this test is not suitable for everyone, because you may not be infertile, but you just don’t have the right sperm or the right connection. Who are the people for whom the fertility assessment is suitable? Infertile couples: couples who have been having intercourse for more than a year without contraception and still cannot conceive, so both infertile couples need to undergo fertility assessment, not only for the male or female partner. 2. People whose fertility may be impaired: for example, couples of advanced age, especially if the female partner is >35 years old, or if the female partner has a long history of smoking. 3, men with a history of exposure to radiation or chemical drugs or a history of treatment. 4. Men who suffer or have suffered from mumps, varicocele, cryptorchidism, prostatitis, vesiculitis or genital itching or painful discomfort. If you are reading this and have decided to read on, it means that you not only love learning, but also most likely fit the above profile, after all, not many people have the patience to read through such a large paragraph. Back to the topic, so what is required for a fertility evaluation? For men, the main tests are routine semen quality tests, including semen volume, liquefaction time, pH, viscosity, sperm concentration, motility, viability, and morphological analysis. In addition, there are special tests including semen biochemical monitoring, enzyme assay, tumor marker test, germ cell analysis, leukocyte analysis, apoptosis monitoring, and chemical elemental score. In clinical practice, the indicators we commonly use are: 1. semen volume Normal semen volume should be 2-6ML, with an average of 3.5ML. If the subject has not discharged semen for 3 days and the volume of one ejaculation is still less than 1.5ML, it should be regarded as abnormal, which may be caused by retrograde ejaculation, low androgen secretion from the testes and dysfunction of the adnexal glands; 2. pH value Normal pH value should be between 7.2-8.0, and when the pH value is >8.0, there is an abnormal ejaculation. When the pH value > 8.0, it is possible that the accessory gland or epididymis has acute infectious disease, while in the case of chronic infectious disease, the pH value may be 7.2 or < 7.2; 3. Assessment of sperm motility, i.e., the motility of sperm, is mainly divided into four grades: a, b, c and d according to WTO standards. If the a-class sperm ≤ 25 or a+b-class sperm ≤ 50%, it is likely to be oligozoospermia, which needs to be treated as soon as possible. In women, the main tests are to check the number of follicles in the follicular pool and are commonly used clinically to check anti-Mullerian hormone; sinus follicle count; and check follicle stimulating hormone. A poor fertility assessment does not kill your dreams of parenthood. The doctor can provide targeted fertility treatment and guidance to the patient, which is the value of fertility assessment.
